Rain caused havoc in Sydney at the 2016 Apia International on Thursday as no singles matches in the men's or women's draw were completed.

In the women's semi-finals, top seed Simona Halep was leading Svetlana Kuznetsova 5-4 in the first set before the rain came down, while qualifier Monica Puig had raced to a 4-0 lead in her opener against Belinda Bencic.

Here is how things stand following Thursday's truncated action:

The weight of play on Friday will do nothing to help Halep, who has been struggling with an Achilles problem of late, but she must still be seen as the favourite to triumph, especially if she ends up playing Puig in the final.

The world No. 94 has confounded expectations this week with some terrific play, and she will no doubt have been desperately disappointed to have been forced off court having started so well against Bencic.

Indeed, it was clearly a frustrating day for all of the players, including two-time Grand Slam champion Kuznetsova:

Grigor Dimitrov certainly had the momentum in his match against Alexandr Dolgopolov, having come back from a set down to lead by a break in the decider, and he will hope to take the initiative again when they get back under way on Friday.

It is set to be a hectic, but exciting, day of action and, assuming the rain stays away, the women's champion and the men's finalists will be decided come the end of play.
